What are the new Surface Edition chips in the Surface Laptop 4?

Microsoft has launched extra details about the custom-built Ryzen Floor Version processors discovered throughout the Floor Laptop computer four, permitting potential patrons to check them to the 11th-gen Core chips additionally being supplied for this product line.

Microsoft’s Floor Laptop computer four consists of two Ryzen chips: the Ryzen 5 4680U Floor Version, and the Ryzen 7 4980U Floor Version. These are semi-custom processors, co-developed by AMD and Microsoft, they usually required some specialised engineering. They’re not offered by AMD, and may’t be present in every other laptops. Due to the advance growth time, they’re constructed on AMD’s older Zen 2 structure, quite than the Zen three foundations of the brand new Ryzen 5000 Cell chips.

On the Floor Laptop computer four launch, we didn’t even know what these chips have been. We suspected that they have been derivatives of AMD’s Ryzen 4000 Cell lineup, however the variety of cores, the variety of threads, clock speeds, and extra have been all a thriller. AMD nonetheless hasn’t printed specs. A Microsoft support document, nonetheless, explains the important thing options of those new processors. 

As we suspected, the Ryzen 5 4680U is a six-core, 12-thread chip, whereas the Ryzen 7 4980U is an Eight-core, 16-thread chip. That, proper there, is noteworthy: the Ryzen 5 3580U and the Ryzen 7 3780U contained in the Floor Laptop computer three have been each quad-core processors.

Microsoft got here out swinging with claims that the Floor Laptop computer four supplied vital efficiency enhancements over the Floor Laptop computer three. These claims seem like true, in keeping with our preliminary testing, and the extra cores and threads are an enormous motive. The complete specs are beneath.

Microsoft printed the specs for the AMD Ryzen Microsoft Floor Version processors within the Floor Laptop computer four.

We additionally now know that the Ryzen 5 4680U runs at a 2.1GHz base clock, and boosts to four.0GHz. The Ryzen 7 operates at a 2.0GHz base clock, and boosts to four.4GHz. This places these chips inside spitting distance of AMD’s current 4700U and 4800U, as we’ve added in AMD’s personal graphic, beneath.

Lots of the different traits of the brand new Floor Version chips will curiosity solely hardcore fanatics. They’re sadly not full, both—Microsoft has informed us what number of GPU cores every chip has, for instance, however not at what frequency they function.

Microsoft printed the specs of the 11th-gen Core i5 and Core i7 that the Floor Laptop computer four makes use of in the identical weblog publish. The small print of those Tiger Lake chips are extra well-known, and Microsoft supplies a hyperlink to Intel’s database on each the Intel Core i5-1145G7 processor and the Intel Core i7-1185G7 that the Floor Laptop computer four makes use of. Right here, it’s price noting that each Tiger Lake chips have solely 4 cores and eight threads.

There are two different comparative particulars price calling out on this technical doc—delicate reminders of the relative strengths of each AMD and Intel. Of the 2, solely AMD’s Floor Version chips point out the manufacturing course of, particularly that they use TSMC 7nm FINFET know-how. Intel’s part leaves out the truth that Tiger Lake is caught on 10nm, a technology behind AMD (at the least on paper). Likewise, AMD’s Floor Version chips pass over the sort and velocity of DRAM they use—DDR4. Intel’s Tiger Lake part describes the reminiscence know-how, and that the Tiger Lake chips are accompanied by sooner, extra superior DDR4X reminiscence.

All of that is helpful info, to make certain. Nonetheless, the actual take a look at will likely be in our evaluate of the Floor Laptop computer four. We’re testing one of many Ryzen variations proper now, so keep tuned.
